4 Claims.

This invention relates to a new and improved spraying device and moreparticularly to a device for manual operation in connection with aliquid receptacle for spraying liquid contained in the receptacle.

The present device is particularly adapted for use in connection withbottles, cans or other receptacles containing fluid which it is desiredto discharge in the form of a spray. Examples'oi l0 such materials areinsecticides of various types, lacquers or paints, and polishing fluidsto be sprayed on glass, metal or wood. Materials of these types arevolatile in character or contain important volatile constituents whichshould be retained in the material.

Sprayers for similar purposes as developed in the past have comprised apump to be located in the receptacle and movable pumping members ordischarge tubes extending through the 0 cover of the receptacle. Thesemovable members reciprocate throughl the cover and the loosely fittingcontact with the cover has been a point of leakage of liquid, as well asa point throughl which evaporation may take place. With such devices itis impractical to ship the container with the pump in place therein, asconsiderable leakage would take place in transit. It has been customarytherefore to provide a separate imperiorate cover for shipping use. Thisseparate cover is an additional expense and further the separateshipment of the pump or spray device necessitates larger cartons andshipping and display packages. Further, a loss of iluid by evaporationor by spilling if the container is upset, will take place after the pumpor spray device has been placed in the container for use.-

It is an object of the present invention to provide a new and improveddevice for spraying liquids.

It is a further object to provide a device of this character adapted tobe locked in a receptacle in a manner to prevent leakage from thereceptacle. f

It is also an object to provide a construction in which the mechanismmay be readily locked against leakage and unlocked for use by a singlesimple movement.

It is an additional object to provide a device which is simple in designand construction and adapted for commercial production and'use.

Other and further objects will appear as the description proceeds.

I have shown a preferred embodiment of my invention in the accompanyingdrawing in ,55 which- Figure 1 is an elevation of the device attached toa bottle, and locked against leakage;

FigureZ is a transverse vertical section taken on line 2 2 of Figure 1on an enlarged scale;

' Figure 3 is a View on an enlarged scale and similar to the upperportion of Figure 2, but showing the device unlocked;

Figure 4 is a horizontal section on an enlarged scale taken on line 4-4of Figure 2; and

Figure 5 is an enlarged vertical section taken on line 5-5 of Figure 2.

In the drawing the receptacle II has been shown as comprising a glassbottle having the opening I2 surrounded by the neck or flange I3. ThisangeIS has screwed thereon the cap I4, which also constitutes the basemember for the spray pump construction. The guide member I5 is clampedbetween the cap I4 and flange I3, and the felt washer I6 and bre washerI'I serve to maintain a tight fluid-proof connection. The 20 guidemember I5 is provided with the sleeve p ortion I8 which receives-thetubular .plunger I9.V This plunger I9 passes upwardly through theopening 20 in the cap I4. The opening 2D, as best shown in Figure 4, iscircular in character except 25 for an enlarged portion 2I, the purposeof which will appear hereafter. i

The plunger I9 carries the collar 22 having the locking lug 23 extendingtherefrom. Immediately below the collar 22 the plunger I9 carries the 30rubber packing washer 24. The upper end 25 of this plunger extendslaterally and carries a discharge nozzle 26 provided with a smallopening 21. Inside of the nozzle 26 is tted a member 28 which isexternally screw threaded and serves to assist in atomizing or I'lnelybreaking up vthel liquidtobe discharged from the nozzle. The' operatingring 29 extends above the laterally extending portion 25 of the plungerand has its two ends 30 formed to t about the plunger, these ends beingretained in place against the plunger by the collar 22.

As shown in Figure 2, the lower end of the plunger I9 carries the piston3I having the packing 32 and fitting within the pump cylinder 33. Thelower end of the cylinder 33 is crimped at 34 to retain in place thevalve seat 35 and also to afford clearances for the passage of fluidinto the bottom of the pump chamber. The ball valve 36 ts on seat 35 andis retained in place by cage 50 31. This cage or spider 3T is retainedin place by the spring 38, the other end of which bears .against thelower face of the piston 3|. v

In assembling the device upon a bottle or other container, the pumpcylinder 33 and plunger I9 are introduced into the bottle and the basemember or cap I 4 is then secured to the bottle or other container,closing the opening therein. The cap Id retains the guide member I5 inplace, the sleeve portion i3 of this guide member serving to guide thereciprocating movement of the plunger in the pumping operation and tomaintain it against lateral displacement. 'Ihe parts are normally in theposition shown in Figure 3. When it is desired to ship the article orput it away for future use, the plunger and its associated parts areforced downwardly by pressure upon the ring 29. During this downwardmovement the parts are turned so that the lug 23 passed through theextended portion 2l of the perforation 2li in the cap I4. After the lug23 is passed below the cap, the plunger is turned to bring the lug 23 tothe dotted-line position of` Figure 4. The cap III is provided with thedepressed portions 39 to restrain the lug against accidental lateralmovement such as tobring it in registration with the extended portion 2|of the opening. When the parts are broughtto the locked position, whichVposition is shown in Figures 2, 4 and 5, the rubber packing member 24 iscompressed against the upper face of the guide member I5 forming aHuid-tight joint about the` plunger Iii-and between the plunger and theguide member.

To restore the device to operating position it 'is simply necessary toturn thev head of the plunger to bring the lug 23 in registration withopening 2l and as soon as it reaches thisposition thespring 38 willforce the plungerupwardly to the position shown in Figure 3. Theplunger-may beY reciprocated for pumping without depressing itsuiiciently to bring the lug 23 below the level of the top of the capI4. It will be understood thatV the sprayer is operated by pressingdownwardly onY the plunger, which may be done by placing the forenger ofthe hand-through the ring 29, the bottle being graspedfinY the palmof-the hand. Each downward movement of the plunger will force a finespray through thel opening 21 in the nozzle Y26. The spring 38 willreturn the plunger to its upper position so that the operator needmerely press down on the ringy repeatedly in order to cause the purnpland spray to function.

The construction shown is simpleY in design and adapted for commercialmanufacture and use. With the parts in the position shown in Figure 2the assembly is lockedagainst leakage and the pump and receptacle may bepacked-in" a small Vcarton and shipped without danger of loss.

` Similarly, if the uid contained inthe receptacle is volatilein-character or contains volatile constituents, Ythe receptacle may belocked against evaporation or spilling of-.the liquidby bringing theparts to locked position.A

While I have shown one preferred embodiment of my invention it is to beunderstood that it is capable of modification to meet varyingrequirements and uses and to t it to other types of receptacles. Itherefore contemplate such changes and modifications as come within thespirit and scope of the appended claims.
